Alpha intrusion into NREM · sigma 11.15–15.81 Hz · N2
As the stage gate opens, alpha intrusion into NREM, catching the transition into this stage plays out under N2 sleep at 11.15–15.81 Hz (sigma). Chemistry here runs GABA, glutamate, orexin, and the markers people report are brief autonomic flicker, light sleep feel, muscle tension pockets, transition tone shift. Gauges read 35/74/41 (atonia/arousal/coherence).

Dataset readout: Alpha intrusion into NREM in N2 (onset). Cortical window 11.15–15.81 Hz (sigma). Atonia=N/A. Markers drive the text below — not dream-symbol meanings.
- brief autonomic flicker
- light sleep feel
- muscle tension pockets
- transition tone shift
Transmitters in this row:
- GABA
- glutamate
- orexin
Mechanism stack
- Cortically, this row runs sigma at 11.15–15.81 Hz while alpha intrusion into NREM, catching the transition into this stage plays out in N2 sleep.
- Chemistry is GABA-led here (inhibitory tone rises across cortical and spinal targets), with glutamate, orexin co-listed; density 102.4 on this row.
- Dataset row #73664235: atonia 35/100, arousal 74/100, coherence 41/100 — the brake is engaged but not complete, set against a noisy, broken backdrop.
- On this onset row the markers stack as "brief autonomic flicker" → "light sleep feel" → "muscle tension pockets" → "transition tone shift" — building as the stage gate closes.
- The BODY line on this page leans on "brief autonomic flicker" for this onset/N2 row — read as mechanism, not dream-symbol shorthand.
The Lab treats "brief autonomic flicker" as a mechanism marker when it shows up at stage entry in N2 sleep — not something to look up in a dictionary.
Felt on waking
On waking, the marker named most often is "brief autonomic flicker" with "light sleep feel" close behind. Because this row sits at onset in N2 sleep, it is easy to mistake for a stray thought rather than a body event.

How Lab Search uses this row
When your recall names "brief autonomic flicker" — tied here to GABA activity, Lab Search reads it as body-side evidence for the BODY line of the matching page rather than as a symbol. It adjusts the mechanism ranking for N2 sleep instead of guessing at what "brief autonomic flicker" might "mean".

How to read Alpha intrusion into NREM · sigma 11.15–15.81 Hz · N2
This row is Alpha intrusion into NREM in N2 (onset). Cortical window 11.15–15.81 Hz (sigma). Atonia state: N/A. Density 102.4. Chart seed 73664235 is deterministic for this URL — the trace is a model of the row, not a clinical EEG.
Gauges on this page: atonia 35, arousal 74, coherence 41. Markers: brief autonomic flicker, light sleep feel, muscle tension pockets, transition tone shift. Transmitters tagged: GABA, glutamate, orexin. Those fields are why two “similar” titles are not duplicates. If a marker did not happen to you, say so — do not wear the whole row.
What the body is doing — not what the image “means”
On waking, the marker named most often is "brief autonomic flicker" with "light sleep feel" close behind. Because this row sits at onset in N2 sleep, it is easy to mistake for a stray thought rather than a body event. The Lab treats "brief autonomic flicker" as a mechanism marker when it shows up at stage entry in N2 sleep — not something to look up in a dictionary.
- Cortically, this row runs sigma at 11.15–15.81 Hz while alpha intrusion into NREM, catching the transition into this stage plays out in N2 sleep.

How Lab Search should use this row
When your recall names "brief autonomic flicker" — tied here to GABA activity, Lab Search reads it as body-side evidence for the BODY line of the matching page rather than as a symbol. It adjusts the mechanism ranking for N2 sleep instead of guessing at what "brief autonomic flicker" might "mean". Then open Decode if you also have a plot. The plot is optional; the body line is not.
This utility will not treat Alpha intrusion into NREM as a spirit, a pregnancy test, or a death omen. It will treat it as a stage-bound somatic metric. If symptoms are nightly, worsening, or include dream enactment, that is clinical, not catalog.
A note from Vigen
I am Vigen. I left Alpha intrusion into NREM · sigma 11.15–15.81 Hz · N2 in the catalog because the gauges (35/74/41) plus markers (brief autonomic flicker, light sleep feel, muscle tension pockets, transition tone shift) are enough to be useful. If they were not, this URL would stay noindex.
